NHF-ST-1R

 

AWS ER-RCoCr-C

Commonly called satellite 1

 

NHF-ST-1R is the highest hardness standard alloy in the group of cobalt alloys used for elevated temperature abrasive wear associated with corrosion. Deposits of this alloy have a large volume of chromium carbides that impact outstanding abrasive wear resistance. The addition of tungsten enhances high temperature hardness and matrix toughness for excellent adhesive and solid particle erosion wear resistance. It bonds well with all steels, including stainless.

 

NHF-ST-!R is used in the following applications

Mixer seals and rotors

Chemical valve balls and seats

Cement handling system

Oil drilling tools

Paper-pulp components

Extrusion screws

Steel mill components

 

NHF-ST-1R is a solid wire product used for TIG and brazing applications. MIG wire for this item is not available.
